Efforts are being made to prevent traffic accidents within the child protection zone. Efforts are being made to prevent accidents by enacting safety facilities and laws to prevent traffic accidents in the school zone. However, traffic accidents in school zones continue to occur. If the driver can know the situation in the child protection zone in advance, accidents can be reduced. In this paper, we design a camera that eliminates blind spots in school zones and a number recognition camera system that can collect pre-traffic information. Design a LIDAR system that recognizes vehicle speed and pedestrians. Design an LED guidance system that delivers information to drivers without smart devices. We study time series analysis and artificial intelligence algorithms that collect and process pedestrian and vehicle information recognized by cameras and LIDAR. In the artificial intelligence traffic accident prevention system learned by deep learning, before entering the school zone, the school zone information is sent to the driver through the Force Push Service and the school zone information is delivered to the driver on the LED sign. try to reduce accidents.

Efforts are being made to prevent traffic accidents in the school zone in advance. However, traffic accidents in school zones continue to occur. If the driver can know the situation information in the child protection area in advance, accidents can be reduced. In this paper, we design a camera that eliminates blind spots in school zones and a number recognition camera system that can collect pre-traffic information. It is designed by improving the LIDAR system that recognizes vehicle speed and pedestrians. It collects and processes pedestrian and vehicle image information recognized by cameras and LIDAR, and applies artificial intelligence time series analysis and artificial intelligence algorithms. The artificial intelligence traffic accident prevention system learned by deep learning proposed in this paper provides a forced push service that delivers school zone information to the driver to the mobile device in the vehicle before entering the school zone. In addition, school zone traffic information is provided as an alarm on the LED signboard.

This study aims to prevent secondary traffic accidents with high severity by overcoming the limitations of existing traffic information collection systems through analysis of traffic information collection detectors and various algorithms used to detect unexpected situations. In other words, this study is meaningful present that analyzing the 'unexpected situation that causes secondary traffic accidents' and 'Existing traffic information collection system' accordingly presenting a solution that can preemptively prevent secondary traffic accidents, intelligent traffic information collection system that enables accurate information collection on all sections of the road. As a result of the experiment, the reliability of data transmission reached 97% based on 95%, the data transmission speed averaged 209ms based on 1000ms, and the network failover time achieved targets of 50sec based on 120sec.

본 시스템은 어린이보호구역에 발생하는 차량사고가 불법주정차된 차량으로 인한 사각지대에 의해 발생되는 것에 착안하여 보행자를 인식하여 운전자들에게 알려 안전운전을 유도하여 사고를 예방해 주는 시스템이다 본 시스템은 영상인식장치, 경광장치, 중계장치, 차량 내 경고장치, 원격 트래픽 경고 수신기로 구성되어 있으며 영상인식장치가 edge-TPU 장치를 활용하여 카메라로부터 입력받은 영상을 모바일넷 기반의 딥러닝으로 처리하여 보행자, 차량, 그밖의 물체를 인식한다. 보행자가 인식되면 외부에서 경광장치가 발광하여 신호를 보내고, 중계장치를 통해 차량 내 경고장치로 보행자 경고 신호를 보낸다. 실험 결과 영상인식을 통해 보행자와 차량을 분류 인식할 수 있음을 확인하였다. 이러한 시스템은 어린이 보호구역에서 발생할 수 있는 교통사고를 방지하기 위해 효과적임을 확인할 수 있었다.
